Wimonpak is a very nice host and the apartment is perfect to stay in and trying a little bit of real Bangkok taste.
It is not in the centre but that's not a problem at all because with tuc-tuc, collective bus or taxis is just a (interesting) ride until the next Boat or the Sky Train Station.
I would definitely would go back again, because the place offers a bit of quietness and with the street food and the 7/11 you find around, there is no need to go to any other place to find everything.
